Tips of CNC Machining Drawings for Faster Quotation
When we get an inquiry from customer, we always ask customer to send 3D drawing and 2D print. Why we want to get them? It is really important for supplier to get a quick quotation out.
More tips of CNC machining drawings for getting a faster quotation
If possible, please provide both 3D drawing and 2D print. ( 3D drawings has IGS, STEP, X_T, UG format, 2D drawing has PDF, JPG formation.)
They should be consistency, which means, the geometry and dimensions are match with each other. For the 3D drawing, we can get a solid model for machine programming; for the 2D print, we can use it as a reference throughout the machining. So if the customer can provide both, it is really better for supplier.
Engineer is always a key factor to judge the drawing.
Always when we get the drawing, we will discuss it with our engineer. Is the drawing ok to produce? Is there any part that is difficult to machining and need to discuss with customer to modify? Could we make them cheaper? So providing a drawing with detail information is really necessary and make things easier to get a faster quotation and best suggestion to get a cheaper price.
Easy text to read is a necessary.
The lines of text should be dark enough to see clearly. To avoid any mistake and guess, using color such as light grey, blue and yellow is not a good choice. They are very difficult to read and doesn’t scan or fax well.
To reduce the likelihood of mix ups, it is better to give all parts unique names.
Marking the full tile block on any revisions, the requested material and finishes.
Hand drawing is also acceptable.
For some customers, they really don’t have 3D drawing and formal 2D print. How do they get a faster price from supplier? Usually a hand drawn diagram is also acceptable by a professional supplier. But on the hand drawing, it must include the exact dimension, clear tolerances ,requested material and order quantity.
Tolerance effects the price a lot.
Sometimes, why the price is so different with a nearly same drawing? The reason is different tolerance. If it is absolutely necessary, please avoiding any high specification tolerances such as “.00XX”. The higher the tolerance is , the much more expensive the price is.
